A ski binding attachment ( 3 ) comprising:—an attachment plate ( 60 ) designed to be mounted on a ski,—an exchangeable fastening element ( 30 ) designed to be detachably mounted on a forward part of the attachment plate ( 60 ), where the attachment plate ( 60 ) and the fastening element ( 30 ) comprise respectively one or more first locking elements ( 301   a,    302   a ) and one or more second locking elements ( 311   a,    312   a ), the first locking elements ( 301   a,    302   a ) and the second locking elements ( 311   a,    312   a ) engaging with one another and locking the fastening element ( 30 ) in the longitudinal and lateral direction of the attachment plate ( 60 ) when the fastening element ( 30 ) is arranged from above and down onto the attachment plate ( 60 ).

TECHNICAL FIELD

The present invention relates to a system for attaching a ski binding to a ski, which facilitates simple replacement of individual components such that the same ski binding system can be adapted to the individual skier's needs.

BACKGROUND ART

Ski bindings have throughout time been attached to skis in a number of different ways. Earlier, the most common way was to screw the bindings in place on the skis. If the bindings were damaged, or it was desirable to move the bindings, they had to be unscrewed and new ones screwed in place. This can affect the properties of the ski, and for a number of skis where weight and flexibility are of crucial importance, the area designated for attaching bindings in this way has been limited or eliminated.

Recently it has become more common to use mounting plates that are attached to the ski once, either by screwing the plate onto the ski, by gluing or a combination thereof.

The binding can then be attached to the ski and in some cases adjusted according to the user's physical characteristics, such as, for example, weight and personal requirements.

Solutions have been proposed that allow the bindings to be adjusted in the longitudinal direction even after mounting. This will be an advantage where it is desirable to be able to make optimal use of the ski's glide and grip properties during a ski trip.

In this respect, there are both manual solutions for adjusting the ski binding, such as, e.g., moving a lever to alternate between two positions, turning a wheel, or an electric actuator capable of being controlled from the ski pole, which pushes the binding along the mounting plate.

Different user groups will require different solutions, and the most advanced users, e.g., in competitive sports are willing to pay more to have the lightest and most functional equipment. For less advanced users who perhaps do not use the skiing equipment so frequently, it will often be of no importance whether the equipment weighs a little more or has a little less functionality, as long as the user is able to have the same positive skiing experience.

However, it would be an advantage for the users to be able to upgrade their skiing equipment or replace components without having to purchase complete new pairs of skis if the user, e.g., wishes to become a more active skier.

If the user, e.g., has skis with fixed bindings and would like manual adjustment of the bindings in the longitudinal direction, it would be an advantage to be able to use the same binding, and only change the adjustment mechanism.

Another user perhaps already has manual adjustment, but would now like to go one step further to electric adjustment. Again, it would be an advantage to be able to replace only the absolutely necessary parts.

In yet another example, it is possible to conceive of a user who already has an adjustment mechanism he is satisfied with, but wishes to change to another or more advanced type of binding. Here, it would be an advantage to be able to change only the bindings.

In this way, users can from the moment they purchase skis with bindings plan for a possible later upgrade. They can, e.g., choose to invest in good skis, but put off buying electric adjustment of the bindings until they have seen how the skis function.

This shows that users will have different needs, and also needs that vary over time. There is therefore a need for a ski binding system that meets these needs in that it has the necessary flexibility.

At the same time it is important that the parts that are reused by both the advanced and less advanced users both have the necessary strength and low weight that are required by the advanced users, and also are sufficiently inexpensive for the less advanced users. This applies to, e.g., the mounting plate or plates.

BRIEF SUMMARY

The invention is in an embodiment 1 a ski binding attachment as defined in independent claim 1.

An advantage associated with the use of the attachment mechanism according to the invention is that several different binding types can use the same attachment plate or mounting plate as a platform to obtain a different type of functionality by changing the elements in the attachment mechanism located on the platform.

This also makes it possible to alternate between different ways of attaching or adjusting the ski binding in the longitudinal direction, depending on the needs of the individual user.

The different elements on the attachment plate can be changed without using tools.

The attachment mechanism takes up forces from the kick in the longitudinal direction.

The attachment mechanism is compact and has little vertical height. Thus, overall low height over the ski is obtained for the whole system.

In an embodiment, the first locking elements are projecting elements that extend out from the fastening element and the second locking elements are opposing constrictions or apertures in the attachment plate.

Thus, the attachment plate can be low in height, thereby making it easy to mount other elements, such as, e.g., a ski binding that can be slid onto the attachment plate if this is integral with the mounting plate for the binding.

In an embodiment, the ski binding attachment comprises a vertical lock designed to lock the first and the second locking elements to each other in the vertical direction.

The largest forces acting on the fastening element are the forces in the longitudinal direction. As mentioned, the longitudinal direction is already locked by reciprocal configuration of the fastening element and the attachment plate. In the vertical direction there are smaller forces, and by separating the locking in the vertical direction from the longitudinal direction, the actual lock in the vertical direction is made smaller than if one lock were to be used for all directions.

In a vertical direction, the vertical lock comprises at least one pin. In this way, an attachment is obtained that is strong, that is easy to operate without tools and that is low in height.

In an associated embodiment, it has a rectangular cross-section. One or more of the surfaces in the cross-section can be horizontal.

In an embodiment 6, which can be combined with any one of embodiments 3 to 5, the ski binding attachment (3) comprises a lock (44 a, 45 a) designed to lock the pin (41 a) in the longitudinal direction when the vertical lock (40) locks the fastening element (30) in the vertical direction.

In an associated embodiment, which can be combined with the embodiment above, the pin (41 a) comprises notches (44 a) or juts that are designed to engage with opposing juts (45 a) or notches in the fastening element (30) or the mounting plate (6).

An example of notches (44A) in the pin (41 a) is shown in FIG. 1. An opposing jut is illustrated in FIG. 4, on the bottom left-hand side. However, this could also be vice versa, such that the notch is in the fastening element and the jut on the pin (41 a).

In an embodiment 7, which can be combined with any one of the embodiments above, the attachment plate (60) is symmetrical about a third longitudinal axis (A3), such that it comprises a second upward directed edge (6 b) on the opposite side to the first edge (6 a).

In an embodiment 8, which can be combined with any one of the embodiments above, the fastening element is symmetrical about a fourth longitudinal axis (A4), such that it comprises one or more first fastening elements (301 a, 301 b) on each side.

In an embodiment 9, which can be combined with any one of the embodiments above, the vertical lock (40) is symmetrical about a fifth longitudinal axis (A5), such that it comprises a longitudinal pin on each side (41 a, 41 b), as shown in FIG. 1.

In all three embodiments 7, 8 and 9 which relate to symmetry, what is meant is that all elements mentioned in the referred embodiments will be symmetrical about axes of symmetry, as illustrated in FIGS. 1 to 4.

In a first associated embodiment above, the vertical lock (40) comprises a mounting bracket (43) which holds the two pins (41 a, 41 b), and where the vertical lock (40) is designed to be locked and opened relative to the mounting plate (6) and the fastening element (30) on application of a longitudinal force on the mounting bracket (43) in respectively first and second opposite longitudinal directions.

In a second associated embodiment, which can be combined with the first associated embodiment above, the vertical lock (40) has a spring force in a lateral direction such that the juts (45 a, 45 b) are pressed into the notches (44 a, 44 b) by the spring force when the vertical lock (40) is in the locking position, and out of the notches (44 a, 44 b) when the vertical lock (40) is not in the locking position.

In an embodiment 10, which can be combined with any one of the embodiments above, the ski binding attachment (3) comprises a rod or a rail (5) disposed, at least partly, between the fastening element (30) and the attachment plate (60), where the fastening element (30) is designed to lock the rod (5) in the longitudinal direction.

In an embodiment 10, which can be combined with any one of the embodiments above, the ski binding attachment (3) comprises a rotatable element (32), rotatably fastened to the fastening element (30), and a first and second rotating pin (321, 322) arranged to rotate with the rotatable element (32), where the rotatable element (32) is designed to be rotated at least one revolution and push the rod (5) in the same longitudinal direction throughout the revolution.

This is illustrated in FIG. 5. In this embodiment, the ski binding moving mechanism (1) comprises an attachment plate (60) designed to be mounted on a ski and a rail (5) or rod arranged to be movable in the longitudinal direction relative to the attachment plate (60).

The ski binding mechanism (1) further comprises a rotatable element (32), rotatably fastened to the attachment plate (60).

A first and a second rotating pin (321, 322), which are also included in the ski binding mechanism (1), are arranged to rotate with the rotatable element (32). Both the rotatable element (32) and the first and the second rotating pin (321, 322) are designed to be rotated at least one revolution and move the rod (5) in the same longitudinal direction throughout the revolution.

In a first associated embodiment, which can be combined with the invention above, the rotatable element (32) is designed to be rotated at least one and a half revolutions and move the rod (5) in the same longitudinal direction throughout the revolutions.

The first and the second rotating pins (321, 322) are not visible at this angle, but will be described below.

The longitudinal movement of the rod or rail (5) is indicated by the arrow M. By the same longitudinal direction is therefore meant forwards in the mounting plate or backwards in the mounting plate.

FIG. 5 also shows a ski binding suitable for being fastened to the rod (5), or where the rod is a part of the binding 5, such that the ski binding (2) is moved forwards and backwards together with the rod.

The ski binding shown here is an NNN toe binding suitable for cross-country skiing, but the invention can be used to move any type of binding providing the rod and the binding are complementary, i.e., are made to be fastened together. Thus, other binding types used in other skiing disciplines can also benefit from the advantages of the invention in cases where it is desirable to have a binding that can be moved in the longitudinal direction, e.g. telemark, randonnée etc.

In a second associated embodiment, which can be combined with the first associated embodiment above, the rod (5) comprises:

-   -   two or more sliding elements (51 a, 51 b, . . . ) arranged one         after another and designed to cooperate with the rotating pins         (321, 322), where the first and the second rotating pin (321,         322) are designed to alternately push the sliding elements (51         a, 51 b, . . . ), and thus the rod (5), in the same longitudinal         direction when the rotatable element (32) is rotated.

In a third associated embodiment that is explained with reference to FIG. 4, an example is shown of how the first and the second rotating pin (321, 322) cooperate with the sliding elements (51 a, 51 b, . . . ) such that the rod can be pushed in the longitudinal direction. A movement sequence including five positions (P1-P5) is illustrated in this figure.

As described earlier, the first and the second rotating pin (321, 322) are arranged to rotate with the rotatable element (32), which is indicated as a broken circle in this instance, such that the pins (321 and 322) are visible. However, the rotatable element (32) can have other types of shapes without this being of consequence for the invention. The pins are indicated as a solid circle and an open circle merely to show their relative position in the sequence that is to be described.

In the first position (P1), the rod (5), and thus a ski binding (2, 4) on the rod (5), are in the rearmost position relative to the mounting rod and the ski. These are not shown in the figure, but for illustration of the further positions in the sequence, it is important to understand that the rotatable element (32) is fixed relative to the longitudinal direction of the mounting plate (6) and the ski.

The first pin (321) here is in front of the first sliding element (51 a), whilst the second pin (322) is between the first and the second sliding element (51 a, 51 b).

In the next position (P11), the rotatable element (32) has been rotated anticlockwise about 45 degrees, and the rod (5) has been pushed a short distance forward because the second pin (322) has moved forward and to the right as a result of the rotary movement, as illustrated by the black and white arrow. Due to the forward movement of the second pin (322) whilst it abuts against the rear of the first sliding element (51 a), it thus forces the rod forward.

In the subsequent position (P12), this becomes even clearer. Here, the rotatable element (32) has been rotated anticlockwise about 90 degrees, and the rod (5) has been pushed a little further forward because the second pin (322) has moved even further forward as a result of the rotary movement.

In the next position (P13), the rotatable element (32) has been rotated anticlockwise about 135 degrees, and the rod (5) has been pushed a little further forward. Now, however, the second rotating (322) has moved forward and to the left since the last position (P12).

In position 2 (P2), the rotatable element (32) has been rotated anticlockwise about 180 degrees, and the rod (5) has been pushed a little further forward. The second pin (322) has moved forward and to the left since the previous position (P13), and has continued to push the first sliding element (51 a) and the rod (5) forward.

In position 2 (P2), the second pin (322) is still located between the first and the second sliding element (51 a, 51 b), whilst the first pin (321), which to begin with was in front of the second pin (322), is now behind the second pin (322), more precisely between the second and the third sliding element (51 b, 51 c).

Another way of explaining how the rod (5) is pushed forwards is to look at it as though the pins (321, 322) climb backwards on the sliding elements (51 a, 51 b, . . . ) when the rotatable element (32) is rotated anticlockwise. As the rotatable element (32) is fixed in the ski, the rod (5) must be pushed forward. The rod is during the half revolution pushed forward a length L1, as shown in the figure.

In position 2 (P2), as previously mentioned, the rotatable element is rotated about 180 degrees, or half a revolution. However, it is possible to continue the rotary movement if it is desirable to push the rod (5) and the binding (2) even further forward.

Although it is not illustrated in FIG. 6, the skilled artisan will understand that a continued rotation of the rotatable element (32) anticlockwise in FIG. 6, starting from position 2 (P2), will result in the first pin (321) now beginning to push on the rear of the second sliding element (51 b) in the same way as the second pin (322) in the previous half revolution pushed on the rear of the first sliding element (51 a). During the next half revolution in the same direction, the rod (5) will thus be pushed forward another length L1, to a position 3, not shown in FIG. 6, where the second pin (322) is now located between the third and fourth sliding element (51 c, 51 d).

In position 3, it will still be possible to rotate the rotatable element (32) anticlockwise. After another half revolution, the rod (5) is in a position 4, not shown in FIG. 6, where the first pin (321) is behind the fourth sliding element (51 d).

In an embodiment 11, which can be combined with any one of the embodiments above or any one of their associated embodiments, the ski binding attachment (3) comprises an electric motor fixedly arranged relative to the fastening element (30), where the electric motor is designed to drive the rod (5) in a longitudinal direction, forwards and backwards.

In an associated embodiment, which can be combined with the embodiment above, the ski binding attachment (3) comprises a drive mechanism between the electric motor and the rod (5) which comprises one or more of the group comprising: a gearwheel, a wire, a chain, a toothed rack, a worm screw, a worm drive, a piston.

In an embodiment 12, which can be combined with any one of embodiments 9 to 11 above, the rod (5) is a part of a ski binding.

In an embodiment 13, which can be combined with any one of embodiments 9 to 11 above, the rod (5) has an attachment for a ski binding.

In an embodiment 14, the attachment plate (60) is an integral part of a mounting plate (6) designed to be attached to a ski and further designed to hold the ski binding fastened in the vertical and lateral direction. A solution of this kind is illustrated in FIG. 5. The forward part of the mounting plate (6) here may be regarded as the attachment plate (60).

In an embodiment 15, the attachment plate (60) is designed to be separate from a mounting plate (6) designed to be attached to a ski and to hold the ski binding fastened in the vertical and lateral direction. This solution is illustrated in FIG. 7.

Regardless of whether the attachment plate (60) is made integral with the mounting plate (6) or not, the attachment mechanism (3) can be made in the same way.

In an embodiment 16, which can be combined with embodiment 14 or 15 above, the attachment plate (60) or the mounting plate (6) have the same height along their entire length.

In an embodiment 16, which can be combined with embodiment 14 or 15 above, the attachment plate (60) or the mounting plate (6) have the same height along their entire length.

In an embodiment 17, which can be combined with embodiment 14, the height of the mounting plate (6) is greater at the forward part of the mounting plate (6) than at its middlemost part.

In an associated embodiment, the height of the mounting plate (6) gradually increases towards the forward part of the mounting plate (6) under the fastening element (30). The forward part of the mounting plate (6) is otherwise referred to as the attachment plate (60), but in this case the attachment plate (60) is an integral part of the mounting plate.

The rail (5) will thus slide easily along the length of the groove, as the increase in thickness compensates for the curvature of the ski. By using an adjustment mechanism for the ski binding located on the front of the mounting plate (6), i.e., the part referred to as the attachment plate (60), this effect will be even clearer.

At the same time, the extra thickness in the tip will mean that the rail, which otherwise should be as thin as possible, obtains extra strength, such that a fastening element (30) can be anchored in the area that has greatest strength. In addition to the actual improvement in the fastening of the moving mechanism, the forces from the moving mechanism will be distributed evenly over a larger area of the mounting plate, such that it is securely fastened to the ski even when the fastening mechanism is subjected to large loads.

In the illustrated embodiments, which are examples of how the invention can be carried out, different features and details are shown in combination. Although a number of features are described as belonging to a particular embodiment, this does not necessarily mean that these features must be implemented together in all embodiments of the invention. Similarly, features described in different embodiments should not be regarded as excluding combinations with each other. A person of skill in the art will understand that embodiments comprising some of the features that are not specifically described together, but which are also not described as that they are excluded from being combined with each other are a part of the invention. An explicit description of all embodiments will not contribute to the understanding of the invective concept, and thus some of the combinations have been omitted to render the application simpler and shorter.
